The patch / fix ppa:kamalmostafa/linux-kamal-mjgbacklight worked for me! I have a Gateway NV5913u notebook with Ubuntu 10.10 amd64. The Fn keys and the power management slider both work, finally I can see without wearing sunglasses. I had to apply the acpi_backlight=vendor line to disable the old acpi_video0 line. I hope this helps other people, I see that there are a lot of users on the ubuntu forums that could benefit from this info. Thank you very much!
